Hello @ Crachinger!

 

Thanks for posting here at the Community Forums!

 

Can you please share here first your device's MTM (machine type-model) number for us to check its specifications?

 

It can be seen through the device's label/sticker or its original packaging and does usually have a format of 8********R as an example.

 

What exactly are you seeing on the screen when you try to turn it on?

 

Try connecting it to an external display/monitor (if available) and see if it will work.

 

Thanks,

Adriel_Lenovo
